The ML-18 is the newest leap in innovation brought to the industry by ARS. The ML-18 resolves glaring security issues with current mainline switch machines, and further reduces the risk for injury and machine damage in the event of a run through. With power supplied by the 12 volt battery system, it allows much more flexibility in using alternative charging methods and will save thousands in expensive battery systems being used now.

  • Provides direct holding force and monitors that holding force. Holding force is not detectable in traditional mainline machines. 

  • 2-rod design instead of the traditional 3 rod design. Each of the 2 rods has position detection and provides 1500 lbs. of holding force(triple the AREMA minimum requirement.

  • If either rod is disconnected from the switch point, the spring compression force will cause the point detection system to overthrow and immediately indicate that a switch is out of correspondence. The force will maintain a safe position holding the point to the stock rail. ‚Äč


  •  The ML-18 is trailable, meaning it can be run through without damage. With previous mainline machine technology, a run through event would cause major damage to the machine, resulting in more dollars spent for repairs.

  • 2-rod design ensures the holding force is maintained to the points for added safety and security. 

  • Center locking feature for switch installation and any adjustments, to ensure safe interactions with the ML-18.
